Application Guide
| Surface Preparation | The substrate shall be sound, dry, clean and fully cured. Remove dust, laitance, grease, loose layers, mildew and other contaminants; repair cracks or uneven areas before coating. |
| Application Environment | Apply with application temperature 10-35 deg C; relative humidity <= 85%; mixed two-component material used within its pot life. |
| Application Method | Apply by spray, brush, roller. Use compatible thinner/cleaner such as clean water where permitted where specified. Mix, thin and recoat according to site conditions and the coating system requirements. |
Export & Storage Notes
| Safety | Confirm substrate condition, compatibility, mixing ratio and application environment before large-area work. Protect from freezing, rain, contamination and direct exposure before the film is fully dry. Do not use material that has exceeded its pot life or has gelled after mixing. Store sealed in a cool, dry and ventilated place and dispose of waste according to local regulations. |
